EA835 or Audi V6 engines

The Audi EA835 6-cylinder V-engine range was produced from 1990 to 2008 and was installed on the most popular concern models of its time, such as the A4, A6 and A8. There are three generations of engines: with a 12-valve cylinder head, a 30-valve cylinder head and an aluminum block.

Engines EA835 12v

At the very end of 1990, the company’s V6 power unit debuted on the Audi 100 model. The first was a 2.8-liter engine, and a year later there was a 2.6-liter with a smaller piston stroke.

These engines were created from a V8 engine, so they have a typical 90° camber. The cylinder block in the engine is cast iron, with a pair of aluminum cylinder heads and hydraulic lifters. The timing belt drives 2 camshafts and controls a dozen valves respectively.

There were only two engines in this series, although in a number of markets they had other indices:

• ABC (12v, distributed injection, 150 hp / 225 Nm);
• AAH (12v, distributed injection, 174 hp / 245 Nm).

Engines EA835 30v

In 1995, DOHC versions of V6 units appeared, their cylinder heads had 5 valves per cylinder. The new cylinder heads required a complication of the timing and chains between the camshafts were added to the belt.

And the rest of the changes were evolutionary, but the number of models has seriously increased: power units with a volume of 2.4 liters, 2.8 liters, and also 2.7-liter turbo engines were offered.

There were a lot of modifications in this series, here we list only the most famous of them:

• ALW (30v, distributed injection, 136 hp / 230 Nm);
• ARN (30v, distributed injection, 136 hp / 230 Nm);
• ASM (30v, distributed injection, 136 hp / 230 Nm);
• APZ (30v, distributed injection, 163 hp / 230 Nm);
• AMM (30v, distributed injection, 163 hp / 230 Nm);
• AJG (30v, distributed injection, 163 hp / 230 Nm);
• AGA (30v, distributed injection, 165 hp / 230 Nm);
• ALF (30v, distributed injection, 165 hp / 230 Nm);
• APS (30v, distributed injection, 165 hp / 230 Nm);
• ARJ (30v, distributed injection, 165 hp / 230 Nm);
• AML (30v, distributed injection, 165 hp / 230 Nm);
• BDV (30v, distributed injection, 170 hp / 230 Nm);
• AJK (30v, distributed injection, 230 hp / 310 Nm);
• AZA (30v, distributed injection, 230 hp / 310 Nm);
• ARE (30v, distributed injection, 250 hp / 350 Nm);
• BES (30v, distributed injection, 250 hp / 350 Nm);
• AGB (30v, distributed injection, 265 hp / 400 Nm);
• AZB (30v, distributed injection, 265 hp / 400 Nm);
• ASJ (30v, distributed injection, 380 hp / 440 Nm);
• AZR (30v, distributed injection, 380 hp / 440 Nm);
• BBG (30v, distributed injection, 190 hp / 260 Nm);
• ACK (30v, distributed injection, 193 hp / 280 Nm);
• ALG (30v, distributed injection, 193 hp / 280 Nm);
• AMX (30v, distributed injection, 193 hp / 280 Nm);
• AQD (30v, distributed injection, 193 hp / 280 Nm);
• APR (30v, distributed injection, 193 hp / 280 Nm).

Engines EA835 EVO 30v

In 2000, the company’s latest V6 units with multipoint fuel injection appeared. This line of engines was distinguished by aluminum cylinder blocks with an extremely controversial reputation.

Another innovation was phase shifters on the intake and exhaust camshafts. There were not so many modifications this time, we only know 3.0-liter engines:

• BBJ (30v, distributed injection, 218 hp / 290 Nm);
• ASN (30v, distributed injection, 220 hp / 300 Nm);
• AVK (30v, distributed injection, 220 hp / 300 Nm).

Since 2006, these units have begun to replace FSI direct injection engines of the EA837 family.
